MACHINE FOR MANUFACTURING GLASS BOTTLES.

SPECIFICATION forming part of Letters Patent No. 767,578, dated August 16, 1904:.

Application filed July '7, 1902. Serial No. 114,615. (No model.) i

To all whom it may concern.-

Be it known that I, CARL LEISTNER, a subject of the German Emperor, residing at 100 The Avenue, Bruce Grove, Tottenham, London, England, have invented certain new and useful Improvements Relating to Machines for Manufacturing Glass Bottles, of which the following is a specification.

This invention relates to machines for the manufacture of glass bottles and other hollow vessels, and more especially relates to the machines described in Patent No. 7 0 1,055, dated July 8, 1902.

The invention has for its object to provide convenient and effective means for discharging the finished bottle and to shape or work thekparison prior to blowing in the finishingmo According to the invention the bottom mold is provided so as to be capable of being tilted to bring in its place a block forthe shaping, working, or marvering of the parison prior to its being blown in the finishing-mold.

In the accompanying drawings a complete glass-bottle-blowing machine is not shown. The mold-carrying arm and connected parts are alone illustrated, which arm would substitute the carrying-arm 87, carrying the bottom mold m and the connected parts of the machine illustrated in the drawings accompanying the specification of the prior patent of the United States before referred to.

In the drawings, Figure 1 represents a front view, partly in section, of the bottom-moldcarrying arm and its connected parts when the said arm is in the position at right angles to thesupporting pillar or frame of the machine. Fig. 2 is a front elevation corresponding to Fig. 1, in which the carrying-arm is shown near its extreme position that it assumes on the delivery of a finished bottle. Fig. 3 is a side elevation corresponding to Fig. 1. Fig. 4 is a plan view of Fig. 3. Fig. 5 is a view the same as Fig. 2, but showing also the bottom mold and its connected parts. Fig. 6 is a plan View corresponding to Fig. 5. Fig. 7 is a side elevation, partly in section, showing the bottom mold in position closed in by the finishing-mold; and Fig. 8 is a front elevation corresponding thereto.

In carrying the invention into effect the carrying-arm 41 of the bottom mold bis pivoted upon the pivotingpin 90 within a bracket which is secured to the slotted plate 3 by means of T-headed bolts or by other suitable means, the slotted plate 3 being carried upon the supporting pillar or frame 1, and the arm 41 may thus be adjusted in height, as required. y

In the drawings the tension-rods 13 and 14 are shown, the former of which is connected to an operating pedal-lever, while the latter is connected to a spring 17, and the upper extremities of both are connected to the chain by which the gear controlling the opening and closure of the parison and finishing molds is operated in such manner that on the depression of the pedal-lever. the parison and finishing molds are closed, while on the release thereof they are opened by the action of the spiral spring 17 in the manner fully described in the specification of the prior patent before referred to.

On the upward movement of the tensionrod 13 under the action of the spring 17 the angle-lever 77 is rotated on its pivoting-pin 78, the arm of the angle-lever 77 being for the purpose connected to the rod 13 by such means as a slot-and-pin connection. In this movement the finger-piece 79, which is carried upon a pin 120 by the other arm of the angle-lever 77, makes contact with the carrying-arm 4:1 and causes it to move to the side. The extremity of the finger-piece 79 is so adjusted, by means of the adjusting-screw 121,

that contact shall only be made after an interval sufficient for thefinishing-mold to have released the bottom mold'b. In this lateral movement of the carrying-arm 41 the end of the finger-piece 79 will slide down the side of the arm in order to be released at its extreme lateral position, whereupon the carrying-arm 4:1 is returned into its original position concentric with the parison and finishing molds when closed, by such means,'for example, as flat springs arranged on each side'of the carrying-arm or other suitable device for bringing back the carrying-arm into the center line of the machine. In the return movement of the carrying-arm 11 to its original position the finger-piece 79 may be slightly turned down. Shortly before the finger-piece 79 slides off the arm 41 it presses against a bolt 140, provided within a guide on the arm 41, and forces it forward. At the opposite end of this bolt an arm 122, pivoted at 122, is connected, which arm carries a roller 123, upon which lies a single-armed lever 124, pivoted at its lower extremity on the front end of the arm 41. The arm 122 is pivoted upon the carrying-arm 41 in such manner that the radial position of the arm may be changed for the adjustment of its position in relation to the lever 124 and the bolt 140, a curved slot in the arm 122 being provided for the purpose.

The arm 41 carries at its extremity the tooth-rod 44, whose vertical position is controlled by means of a toothed segment or pinion 43 upon the spindle 431, of which a counterbalanced operating-lever 432 is provided, Fig. 6. The operating-lever 482 is so weighted that the whole or nearly the whole weight of the mold is balanced, so that when the bottom mold is released the weight of the finished bottle will carry the mold slowly down from the position indicated in Figs. 7 and 8 to that indicated in Figs. 3 and 5.

The bottom mold L is mounted upon a supporting part 76, pivoted at 125 to the toothed rod 44, and is connected thereto by means of a stud [2, between the head of which and the under face of the supporting part 7 6 a spiral spring 6 is arranged, against the action of which the bottom mold tmay be drawn up accurately into its position on the closure of the finishing-mold upon it. The bottom mold b is provided with a conical edge entering into an annular. groove of corresponding form in the finishing-mold 6 so that thus the bottom mold b will always be brought up into its exact position by the finishing-mold, notwithstanding any inexactness of adjustment or position of the carrying-arm or consequences of expansion and contraction of the parts subject to substantial changes of temperature.

The supporting part 7 6 carries at its side the roller 126, beneath which the lever 124 ies.

In operation it will be understood that as soon as the finger-piece 7 9 presses against the end of the sliding bolt 140 the latter is forced outward, and thereby the lever 124 will make a corresponding movement around its pivot, whereby it presses beneath the roller 126 and effects the partial rotation of the supporting part 76 of the mold 6 upon the axis 125, so that the finished bottle carried by the bottom mold falls down and is conveniently received in an asbestos cradle arranged in a suitable position to receive it. The finger-piece 79 continues its movement further and slides off the face of the arm 41, so that the latter may be returned to its original position by its spring. The bolt 140 acts under the influence of a spring, (not shown in the drawings,) whereby it immediately resumes its original position after the finger-piece 79 has passed off the face of the carrying-arm.

A block m is provided on the supporting part 76 in a position at right angles to the bottom mold b and may be mounted thereon, as illustrated in Fig. 7 so that when the mold b is tilted for discharging the bottle, as hereinbefore described, the block m lies uppermost, and the weight of the mold b is such as to maintain it in that tilted position, as illustrated in Fig. 5.

The carrying-arm 41, it will be understood, returns to its original position after the bot tom mold is tilted, as hereinbefore described, and thus carries the block 721.. If the opera: tive has now swung down the next parison formed in the parison-mold, he will now be able to shape,work, or marver it in the block on before he incloses it for blowing in the finishing-mold. He thus requires only to lift the toothed rod 44 by means of the lever 432 so far that the block receives the lower end of the parison and shapes, works, or marvers it in the known manner. If the desired shape and distribution of the glass is effected, the block on is again lowered and the bottom mold b is brought uppermost, as hereinafter described, and the latter is again lifted. Thereupon the finishing-mold is closed, and the complete blowing of the bottle is effected in such manner as that described in the specification of the prior patent of the United States hereinbefore referred to.

As the exchange for the bottom mold b for the block 722 after the delivery of the finished bottle is effected automatically, it is of course desirable that after the shaping, working, or marvering is eflected the block mshould be automatically exchanged for the mold b. For the purpose an angle-lever 128 is provided at the extremity of the carrying-arm 41 on a pivot-pin 127 and is provided with a weighted arm 129, which serves to cause the other forked arm of the lever to assume the position indicated in Fig. 3 when left to itself.

On the discharge of a finished bottle, as hereinbefore described, the bottom mold 6 strikes against the forked arm of the lever 128 and presses it against the side of the toothed rod 44. If now for the purpose of shaping, working, or marvering the parison the toothed rod 44 is again lifted, the bottom mold 6, moving upwardly, will free the forked arm of the lever 128, so that the latter will, under the action of the weighted arm 129, take up its inclined position, as illustrated in Figs. 3 and 7. If now after the shaping, working, or marvering of the parison the toothed rod 44 is again lowered by the lever 432, the downwardly-directed bottom mold b will contact with the forked arm of the lever 128, so that thereby the supporting part 76 is turned 'upon its axis 125 and the moldb again becomes uppermost, as illustrated in Fig. 3. The mold b is now lifted so far that it takes up the bottom of the parison, whereupon the complete blowing takes place in the finishingmold, which is previously closed upon the bottom mold b. After the blowing is completed and the molds are opened the bottom mold b is again lowered by the weight of the finished bottle,while the carrying-arm is again swung laterally and the finished bottle delivcred, and thus the block m is again brought into the previous position of the bottom mold.
